Mucocutaneous manifestations and their relationship with CD4 T-lymphocyte count in hospitalized patients infected with the human immunodeficiency virus (HIV) in Medellín, Colombia

Introduction: About 80-95% of patients infected with the human immunodeficiency virus (HIV) develop skin manifestations, which are markers of the patients’ immune status. Objective: To describe the dermatologic manifestations and the clinical and sociodemographic factors of hospitalized patients diagnosed with HIV and their correlation with CD4 T-lymphocyte count. Materials and methods: We conducted an observational, cross-sectional, and retrospective study of the medical records of 227 adult patients with HIV diagnosis evaluated by dermatology in a hospital in Medellín, Colombia. Results: We included 227 patient records with 433 dermatologic manifestations, 64.4% of them infectious. The most frequent manifestations were oral candidiasis, condylomata acuminata, and drug reactions. Moreover, a statistically significant relationship was found between disseminated herpes zoster virus and secondary syphilis with a CD4 count between 200-499 cells/mm3 (p=0.04 and 0.028, respectively). There was also a statistically significant relationship between oral candidiasis and a CD4 count of less than 100 cells/mm3 (p=0.008). Conclusions: The relationship between disseminated herpes zoster with CD4 between 200-499 cells/mm3 suggests that, despite having high CD4 counts, severe forms of the disease may occur due to possible T-cell dysfunction and depletion of the immune system. Additionally, the relationship between oral candidiasis and CD4 less than 100 cells/mm3 indicates the potential role of oral candidiasis as an essential marker of weakened immune status in HIV patients.
